Abstract

See full text

A fast acting valve train system for valve deactivation is provided that includes an actuator together with a switchable rocker arm. The actuator, controlled by the engine control unit and mounted to a structural housing, contains an actuator pin that retracts or extends facilitating either a deactivation or reactivation valve event. The switchable rocker arm is a two arm design that includes cam side and valve side arms that are coupled together with a locking mechanism assembly that interfaces with the actuator pin. The system is capable of fast switching times to meet the increased demands of cylinder deactivation systems.
